Lyophilization, also called freeze-drying, is the process of removing water from a sample, often for preservation. Lyophilization involves the sublimation of a sample’s water content, usually through a rapid freezing process. Freezing materials quickly helps avoid the destruction of the cell walls in the sample from the formation of large ice crystals.
DetailsOverview The ability of a material to store and transfer heat is characterized with the material properties of thermal diffusivity, thermal conductivity, and specific heat capacity. Understanding these properties is critical when exposing a material to a wide array of temperature environments: large gradients, rapid changes, and maintaining stability, to name a few. Accurate…

DetailsHydrogels are three-dimensional porous strctures that can absorb large amounts of water. They can be made up of polymers, protein, peptides, colloids, surfactants, or lipids.1 Hydrogels’ ability to uptake large amounts of water is useful for many biological applications, including drug delivery and tissue engineering. Since a hydrogels’ properties change as it absorbs water, scientists must accurately characterize its behavior at different saturation amounts and in varying conditions.

DetailsWhat are bioplastics? How can plastic manufacturers use them to improve the environmental impact of their products? With so many emerging green technologies, producers and consumers need to differentiate between greenwashing1 and genuine advancements. Furthermore, if a new development is deemed environmentally beneficial, all stages of the plastics supply chain, especially converters, must then learn how to incorporate the new technology without undermining their process or products.
